Poster 9: Jerry Howard – Drying and sintering of easily sterilizable and reusable xerogel filters for N95 respirators

<< Return to the Main Page

Faculty mentor: Krista Carlson

We wanted to make reusable filters for N95 masks. We proposed to make them from xerogel, as this is a porous material which can be autoclaved for sterilization. Xerogel is the result of making a sol-gel and drying it at ambient pressure. Making a piece of xerogel large enough to be used as a filter without cracking is difficult. We investigated the effects of diameter on drying time of xerogels. Xerogels with larger diameter showed a longer drying time.
